"There are several accident cases where you can look back and see erosion of basic flying skills," says Rory Kay, ALPA's executive air safety chairman.

Kay was speaking at the unveiling of the union's top safety priorities for the year. Included are calls to shift to a "trust-based" passenger screening system, improving qualifications and training for pilots and combating pilot fatigue.

"Colgan was a recognition that there are issues to address," says ALPA president John Prater, referring to last February's crash of a Colgan Air Bombardier Q400 near Buffalo.

Included in ALPA's shopping list of concerns is that an increased reliance on automation and autopilots is causing pilots to lose basic aircraft handling skills. Babbitt earlier this month said he would bring airlines and human factors experts together this spring to discuss the issue, noting that "several airlines" had told him they were changing operational procedures to call for "a little more hand-flying".

United Airlines has had such guidelines in place for years, says Kay, a pilot for the carrier. Kay says United "actively encourages" pilots to hand-fly whenever possible through verbiage in the flight operations manual.

"They understand that basic skills are eroding," he adds. The practice varies by carrier, with some recommending pilots to engage or disengage the autopilot system as low as 1,000ft (305m). Kay says he typically hand-flies the aircraft below 18,000ft.

ALPA priorities in the security area include encouraging the US Transportation Security Administration (TSA) to move toward a passenger screening process that "identifies people who pose no threat and quickly move them through screening", says the union's national security committee chairman Rob Powers.

Passengers "in whom we cannot place the same trust" would get more initial screening, he adds.

ALPA is also urging the TSA to develop standards for secondary cockpit door barriers that would be installed between the forward galley and cockpit, allowing pilots with a more secure way to use aircraft lavatories.

United has equipped some of its aircraft with seven-wire cable barriers that stretch across the cabin. "It would take more than 7s to breach the gate," says Prater, "which would give pilots enough time to close the cockpit door."

As for new flight and duty time, Prater says any new regulations must be based in science, must apply evenly to passenger and cargo aircraft, for both domestic and international operations, and must include a fatigue risk management system.
